Expression of DOG 1 and correlation with Ki-67 and tumor characteristics in GIST: case series analysis in a tertiary care center

Gastrointestinal stromal tumours (GISTs) are the most common non epithelial, mesenchymal tumours of the gastrointestinal tract and amount to 1 to 3% of all gastrointestinal tumours. Histologically, GISTs demonstrate considerable morphologic variation.The aim of the study was to evaluate the histo-morphological features of GIST and the expression of DOG1 and KI-67 in these tumours. Eleven cases of GISTs received during a five-year period at a tertiary care centre were analysed for their demographic parameters, morphology and risk stratification. Immunohistochemistry for DOG1 and Ki67 was performed for all the eleven cases.Inthis study there was a female preponderance with the mid -fifties being the median age of presentation. The stomach and small intestine were the common sites of involvement. The histologic type was predominantly spindle cell with a few cases of mixed tumours. DOG 1 was positive in all the tumours and Ki-67 index was markedly elevated in the epithelioid cell type and in the high-risk category of tumours.DOG 1 holds good as an important marker for clinically suspected GIST diagnosis and Ki-67 expression correlates with the risk stratification of the tumour and can be a good prognostic factor

Perceptions about training and knowledge of HIV/AIDS ethics among health care providers at teaching hospitals of a medical college in Karnataka, India.

A cross sectional study was conducted to evaluate perceptions of HIV/AIDS ethics among health care professionals at three associate hospitals of Kasturba Medical College Mangalore. A total of 144 health care professionals were included, of which 106 (73.6%) were doctors and 38 (26.4%) were nurses. Only 52.8% of doctors and 56.6% of nurses agreed that they had received adequate training related to HIV data confidentiality. 85.8% of doctors and 76.3% of nurses perceived that they need additional training in HIV policies & procedures. With respect to rights of HIV-positive clients 92.5% of doctors and 84.2% of nurses felt the need for further training. 69% of doctors and 52.6% of nurses agreed that confidentiality could be breached in case of subpoena or other judicial processes.
